We have to work out the relative percentage of each group at a university e.g. Engineering 10%, Social Sciences 15%, English 20%, Sciences 25%, Languages 10%, Law 5%, Medicine 15% The sample must then contain all these groups in the same proportion as in the target population (university students).
Everything you need for your Tie-Dye project: Dyes, color enrichments, fixers, clothing blanks, and more! Tie-dye describes a pattern of color made by preventing the dye from reaching some areas of the fabric by using tight ties of rubber bands, sinew, string, etc., while dyeing others.
If your rug is made from cotton, you can dye it easily with fiber reactive dyes, such as the Procion dyes found in any good tie-dye kit or in the Tulip One Step Fashion dye in the local crafts store.
